In rheumatoid arthritis (RA), CD36 expression in fibroblasts is increased by macrophage-derived inflammatory mediators, including interleukin-1β (IL-1β), IL-6 and interferon gamma (IFN-γ) (Ahmed et al., 2008; Komatsu and Takayanagi, 2012). The gene discussed is IL1B; the disease is rheumatoid arthritis.
